Hi,

the docs for Gst::Element show the methodes  
paused?  
playing?  
ready?

but they are not implemented in the current SVN. Only in  
gstreamer/test/tc\_element.rb are tests for them.

Were they never implemented or removed? I think, they are handy.

Cheers, detlef

They will not be implemeted.  
I forgot the detail but the reason why they were removed is that they  
are not safe.

GStreamer is a multi threaded library.  
In the following code, “element” may not be “paused” in “# something”  
even if  
“element.paused?” is true:

if element.paused?  
# something  
end

Element’s state may be changed in other thread.  
GStreamer provides a signal to handle state change. (Sorry. I forgot  
the signal name)  
You should use the signal to handle state change safely.

# I’m sorry if the description is not correct.

# I don’t have an environment to confirm the case…

P.S. gstreamer/tests/ directory is deprecated. We will remove the  
directory  
after we implement all methods in gstreamer/test/. We also need help  
for the task.

## Thanks,

kou
